Attorney General Eric Holder should not be allowed to investigate the Justice Department's spying on journalists at The Associated Press and Fox News, Oklahoma Sen. Tom Coburn said on Sunday.

"Allowing the very person that authorized the two things we are very aware of today" is inappropriate, the Oklahoma Republican said on CBS's "Face the Nation." There's an inherent conflict of interest in me judging whether I did something and reporting it to the president."
